Growth of a ZIF-8 membrane on the inner-surface of a ceramic hollow fiber via cycling precursors

Abstract

For the first time, a ZIF-8 membrane was grown on the inner surface of a ceramic hollow fiber via cycling precursors. The inner-side hollow fiber ZIF-8 membrane exhibits good performance for recovering hydrogen.

Preparation of continuous NH2–MIL-53 membrane on ammoniated polyvinylidene fluoride hollow fiber for efficient H2 purification

Hollow fiber modules with ceramic-supported PDMS composite membranes for pervaporation recovery of bio-butanol

“…Recently, Brown et al reported a novel and scalable interfacial microfluidic processing approach for fabricating metal organic frameworks (MOFs) hollow fiber membranes [22]. In our previous work, highquality ceramic hollow fiber composite membranes were developed based on various kinds of materials, such as PDMS [23], ZIF-8 [24] and graphene oxide [25].…”

Highly hydrogen permselective ZIF-8 membranes supported on polydopamine functionalized macroporous stainless-steel-nets

“…In the last ve years, more and more effort has been paid to the preparation of ZIF-8 membranes by in situ growth, secondary growth, and also the liquid phase epitaxy method. [16][17][18][19][20][21][22][23][24][25]33 However, it was oen found that separate ZIF-8 crystals or islands rather than continuous layers were formed on the native ceramic supports by direct solvothermal synthetic routes because heterogeneous nucleation of ZIF-8 crystals on the support surfaces was very poor. 17,26 Therefore, seed coating 20,21 or chemical modication 17,26 of the supports have been applied to promote the heterogeneous nucleation of ZIF-8 crystals on support surfaces.…”
